I agree with Kevin B about udev rules.  I think that will solve your problem.

Does it matter where the boards show up in /dev?  For example, you're wanting board A to do the same 
job all the time and board B to do a different job.  But if they can be made and connected all the 
same way then the host can just tell the target at ttyUSB0 to do job A regardless which board it is.

Probably doesn't help but it's a different way to think about the problem.
